I don't make much soap these days. Mainly for personal use. The problem:
The last few batches have failed. (cold process)
After mixing, the soap separates, voids occur filled with liquid. Here's the last formula, a 1200 gram (weight of oil) batch:
water as % of oil weight: 40%
fragrance: 'red berries' 3% (we've used it before without problems)
lye conc: 25.8% (NaOH)
cocoa butter: 15%
coconut oil, virgin: 20%
safflower oil, high oleic: 40%
palm oil: 20%
castor oil: 5%
values were calculated with soapcalc as usual.
On mixing and blending, the reaction seemed to be going too fast. It wasn't expected to be fast; the relatively high % of water and oleic oil should have made it fairly slow. About 20 min after putting in the mould, the soap began separating, voids and oil pockets developed.
I am beginning to think that perhaps our palm oil has gone off. It doesn't smell bad though. However this is about the fourth failed batch. Has anyone any ideas?
